Women's One Piece Swimsuits: The Perfect Blend of Style and Support

 One Piece Swimsuit Styles

A one piece swimsuit covers the torso in a single piece, which gives more coverage and support than a two-piece, and suits swimmers who want secure coverage without adjusting a top. Common styles include scoop neck, high neck, plunge, halter, and tank cuts, with low, medium, or high leg openings. Open-back and cross-back designs add shape, while a classic full back keeps everything secure. Browse the full range of women's swimwear to compare cuts.

One Piece Bathing Suits with Tummy Control

Many one piece bathing suits add shaping panels or ruching through the middle to smooth the waist and flatter the figure. Ruched sides hide the seam and adjust to your shape, and darker colors and diagonal lines slim the silhouette. A one piece bathing suit with tummy control works well for the beach, a pool day, or a vacation when you want coverage and support in one suit.

Fit and Coverage

Fit decides comfort. Adjustable straps set the right shoulder height and keep the suit from digging in. Removable cups add shape and can come out for a natural look. Full-coverage cuts stay put through swimming and water play, while higher-cut legs lengthen the look. For even more coverage, swim dresses add a skirted layer. Check the size chart on each suit, since one piece swimsuits run tight through the torso by design.

Fashion vs. Athletic One-Pieces

A fashion one piece is built for the beach, pool, and everyday swimming, with an emphasis on coverage, shaping, and style. An athletic one piece is cut for lap swimming and training, with a tighter fit and chlorine-resistant fabric. If you swim laps, compete, or need a practice suit, shop athletic and competition one-piece swimsuits instead.

Picking a One Piece Swimsuit

Match the suit to how you will wear it. For sunbathing and casual swimming, comfort and style lead. For active water days, choose a secure fit and straps that stay in place. Shoppers who want a different silhouette can compare tankinis for easy bathroom breaks or bikini tops for a two-piece look.

Fabric and Care

Most one piece swimsuits use a nylon or polyester blend with spandex for stretch and recovery. Rinse the suit in cool water after each wear to clear chlorine and salt, then hang it to dry. Skip the dryer and fabric softener, which shorten the life of the elastic.
